206241 Dubois           Discovered 2002 Nov. 24 by NEAT at Palomar.
Dutch anatomist, surgeon and paleontologist Marie Eugène François Thomas Dubois (1858-1940) was the "founding father" of palaeoanthropology. His dedicated search culminated in 1891 with the discovery of the first Homo erectus fossils in a bank of the Solo river near Trinil, Java. The name was suggested by M. Langbroek.
